DEFINITION MODULE gdbif ;
(* Provides interactive connectivity with gdb useful for debugging
Modula-2 shared libraries. *)
EXPORT UNQUALIFIED sleepSpin, finishSpin, connectSpin ;
(*
finishSpin - sets boolean mustWait to FALSE.
*)
PROCEDURE finishSpin ;
(*
sleepSpin - waits for the boolean variable mustWait to become FALSE.
It sleeps for a second between each test of the variable.

PROCEDURE sleepSpin ;
(*
connectSpin - breakpoint placeholder. Its only purpose is to allow users
to set a breakpoint. This procedure is called once
sleepSpin is released from its spin (via a call from
finishSpin).
